Hi!
My guess is that finding the 150th Ann. wood is going to be difficult if not impossible but I just saw a 760 stock on Ebay and you might try the gun auction sites like Gunbroker & Auction Arms.
Failing all that, I have had some luck with Hoosier Gun Works website and there is always Numrich (Gun Parts Corp). You will find something suitable, it will just take a while.
